No, and, err..no. So the idea of degeneracy is to count the number of possible combinations of quantum numbers that gives the appropriate energy, with the rule that the n's are quantized as integers. So saying that nx = ny = 1, and nz = 3 is the answer isn't rightthat could be one of the ways, but certainly not all; if that's allowed, so is nx = nz = 1, and ny = 3.meegal90 wrote:Is the answer is 3 fold degenerate with nx,ny and nz values 1,1,3 respectively??
Also, you're in a 2D well, so there are only 2 quantum numbers, not 3 (which is fortunate, because otherwise this particular energy state would be impossible). Wikipedia states E = (hk)^2/(8mPi^2), with k^2 = k(dot)k = pi^2/a^2(nx^2+ny^2).http://en.wikipedia.org/wiki/Particle_i ... onal_boxes
So, that should be enough to answer the question, which is really how many ways can you have nx^2 + ny^2 = 25, since everything else is just a constant, the same on both sides, which allows you to cancel.

So the answer is two fold degenerate since quantum numbers can take the value nx=3,ny=4 or nx=4,ny=3. Am i right??

Your college should investigate you for academic dishonesty.

Seriously, the nerve?! No one here owes you an answer, and you don't even attempt to show a proper attempt at the question. Just f*** off, and stop spamming the physics community here, which is meant to be GRE related, and not to help spineless leeches like you.meegal90 wrote:Give the right answer please...
